Website Graphic Design !

Hello,
I have my website up and I would like to know how to make such great designs for it,I have seen many websites and they make me so jealous for their awesome design. I have seen free templates,also paid ones but I never seem to be interested on these things. 
I would like to call out for some templates like great ones, paid or free or if not possible, I would like to know what software to use for making designs.
Thanks,hope this post isn't spam for you guys!
